towards base, especially round apex. Hindwings whitish, faintly yellowish- 

 tinged posteriorly, and spotted with grey ; cilia whitish, with a grey basal 

 line. 



Beniote from all its congeners in superficial appearance ; the peculiar 

 augulated subcostal mark at base, (differing in the sexes), is unique in its 

 way, but only conspicuous in the male. 



Common at Christchurch, Wellington, and Dunedin, generally in 

 gardens, in January, February, March, and August. 



7. Cacoecia, Hb. 



Thorax smooth. Antenna in male ciliated. Palpi moderate or rather 

 long, porrected, second joint triangularly scaled. Forewings in male with 

 strong costal fold. Hindwings broader than forewings. Forewings with 

 12 veins, 7 and 8 separate, 7 to hindmargin. Hindwings with 8 veins, 

 3 and 4 from a point, 5 approximated at base to 4, 6 and 7 separate (rarely 

 stalked). 



Distinguished from Harmologa by the origin of veins 3 and 4 of the 

 hindwings from the same point, from Tortrix by the costal fold of male. 

 Of the species which I originally referred here, four have been satisfactorily 

 determined to be mere varieties, three have been transferred to the neigh- 

 bouring Harmologa, one (of which the male had been unknown) to Tortrix, 

 and one is removed to the Grapholithida?, the basal pectination of the hind- 

 wings having been overlooked. I have now only two true species of 

 Cacoecia from New Zealand; the genus is numerously represented in 

 Australia.

Male, female. — 19-28 mm. Head and thorax varying from ochreous to

 Forewings moderately broad, posteriorly dilated, less in female, costa 

 moderately arched, in female straighter posteriorly, hindmargin sinuate,
